Java Foundations Consider the following Java method to reverse an array, i.e. rearrange its elements to the opposite order. An array containing {1, 3, 5} would contain {5, 3, 1} after being reversed. public static void arrayReverse(int[] array) { int le, ri; for (le = 0, ri = array.length - 1; le < array.length / 2; le++, ri--) { int temp = array[le]; array[le] = array[ri]; array[ri] = temp; } } Write the worst-case runtime efficiency of arrayReverse in BigOh notation.
FOR JAVA Write a Java method that takes two 2 dimensional int arrays (a and b) and a 2 dimensional boolean array (c) where all three arrays have the same size. Your method should return an array (result) such that, if a partic- ular element in c is true, then the corresponding (same indexed) element in result must be the multiplication of the the corresponding elements of a and b. If the element in c is false, then the the corresponding element in result must be the negative of multiplication of the the corresponding element in a and b. For example ifa = {{1,2,3},{4,5}},b = {{1,2,1},{0,2}} andc = {{true,false,true},{false,true}}, then the result should be result={{1, -4, 3}{0, 10}}.
java Given Array :ARRAY[] = [11, 21, 33, 40, 50]Write a full and complete recursive implementation of the Binary SearchAlgorithm such that you find your target element 21 in O(log2(n)) timecomplexity overall and O(1) space complexity. Here, n is the length ofthe list of input integers (array). We will not be considering any memoryused by recursion.

URGENT JAVA Write a Java method that takes two 2 dimensional int arrays (a and b) and a 2 dimensional boolean array (c) where all three arrays have the same size. Your method should return an array (result) such that, if a partic- ular element in c is true, then the corresponding (same indexed) element in result must be the multiplication of the the corresponding elements of a and b. If the element in c is false, then the the corresponding element in result must be the negative of multiplication of the the corresponding element in a and b. For example ifa = {{1,2,3},{4,5}},b = {{1,2,1},{0,2}} andc = {{true,false,true},{false,true}}, then the result should be result={{1, -4, 3}{0, 10}}.
First, write a Java method merge that takes as parameter a non-empty double array representingemployees’ salaries. The method merges the values of every 2 adjacent elements. put themerged values at the beginning of the array, and put 0 in the remaining positions. Suppose thatthe original array will contain an even number of elements.Second, write two java methods readArray(int[]a) and printArray(int[]a) thatreads/writes the elements of an array passed in parameter from/to the standard input/output.Finally, Use the following main method to test your different methods:public class MergeSalary{ private static Scanner input = new Scanner(System.in); public static void main(String[] args) { double[] salaries = new double[10]; System.out.print("Enter 10 salaries: "); readArray(salaries); merge(salaries); System.out.print("Salaries after merge: "); printArray(salaries); }}
Write a program in any language you know to calculate the GCD for a sequence of numbers, let us say 4 numbers, kept in an array. You need to provide two solutions: 1) Iterative solution 2) Recursive solution. Test your code using the following numbers: 1048,1024,1480, 2640. The GCD of these numbers is 8.

hello doctor , I have a qustion about binary search upper bound in java (Explination by code) If I have an array consist of {1,1,1,2,2,2,2,2,4,5,5,6,6,6} how can I do it while x = 3
The solution must be submitted in the Coral programming language. A program that reads a list of 10 integers, and outputs those integers in reverse. For coding simplicity, follow each output integer by a space, including the last one. Then, output a newline. Ex: If the input is 2 4 6 8 10 12 14 16 18 20, the output is: 20 18 16 14 12 10 8 6 4 2 To achieve the above, first read the integers into an array. Then output the array in reverse.
